METHOD FOR PRODUCING OF ANTIREFLECTION COATING Russian patent published in 1995 - IPC

Abstract RU 2037474 C1

FIELD: production of optic elements. SUBSTANCE: adhesive layer of silicium dioxide having optical thickness λ/2 and clarifying coating are applied consequently on optic detail by electron-beam spraying. Mentioned above clarifying coating has alternating layers of silicium dioxide and of compound having refractive index higher than refractive index of silicium dioxide. Layer of silicium dioxide having optical thickness 2-3 λ but divisible by l/2 is additionally applied on adhesive layer of silicium dioxide. All mentioned above layers of silicium dioxide are applied in atmosphere of oxygen. EFFECT: improves efficiency of the method. 2 dwg
